The following settings are made for the EQN1325 encoder: • The encoder power supply is set to 5 V • Number of revolutions to 4096 • Signal periods per revolution 8192 After the mode has been set, the zero position is determined, and the starting values for the position and the speed output at the connections. In the standard mode, the block can assume four different statuses: • NRM The values read-out from the SBM2 module (position and speed) are displayed at the block connections. If an error is detected, the block goes into the ERR error condition. • ERR The following errors can occur in operation: • Encoder is defective or is not connected • Encoder was disconnected • Data transfer error for serial communications between the encoder and SBM2 module • SBM2 module not available In the first three cases, the block goes into the "INI“ initialization status and in the latter case into the "OFF" status. 1-2 Function Blocks - FM 458-1 DP Edition 03.2003 Input/output blocks • INI as for the "initialization phase“ mode • OFF Output QF is set and processing terminated.

This signal also generates the interrupt for the interrupt task in which the block is configured. The contents of the register are then read-out and the values for the output connections computed. DM=1 SBM in cyclic tasks If the block is computed in cyclic tasks, then the SBM2 module register is read-out in the system mode. The contents of the register are then read-out in the normal mode and the values for the output connections computed.

This diagnostics data correspond, with the exception of the maximum possible length, to EN 50170. According to this Standard, the diagnostics data can be a maximum of 244 bytes long. The function block supports a maximum of 240 bytes On the EXM448, there are restrictions regarding the quantity of diagnostics data. Only diagnostics data (Standard diagnostics data) is supplied which the function block DIAPRO supplies. Note The consistency of the outputs is not ensured. When new diagnostics data is received, some of the outputs can have "New" information and some can still have "old" information. Mode of operation The PROFIBUS-DP interface is selected using connection CTS. The function block only enters a communications error for errors, which are detected during initialization. A communications error cannot be acknowledged and the function block DPSLDG is only used for diagnostics. This means, that in normal operation, a communications error is not entered. Only the cause of the error is signaled at output YTS.

If a function block is configured a multiple number of times, this is detected when initializing, and results in an entry in the communications error field. • The block may only be configured in the sampling interval 32 ms <= TA <= 255 ms. Otherwise, an entry is made in the communications error field. Mode of operation When initializing the function block, general preparations are made to enable the coupling. The coupling is only enabled after the standard mode has been run-through (executed) several times. After the coupling has been enabled, the central block monitors that senders and receivers are correctly registered. Further, if required, it reorganizes and updates the block output CDM at each processing cycle. The function block cannot be used to initialize another P-bus coupling or monitor this. It can only initialize its own P-bus coupling on which CPU is configured. An entry is made in the communications error field if another module name is specified at the CTS input (other than its own). The CDM block output provides information about the coupling status. The connection is a 1, if the coupling is enabled for general send/receive operation. The CDM block output is 0, as long as the coupling is still being initialized, or is being re-initialized (after a temporary fault). 2-14 Function Blocks - FM 458-1 DP Edition 03.2003 Communication blocks I/O CTS The configured name of its own CPU is specified at this initialization input.

A SIMATIC-CPU can transfer up to 128 bytes to the FM 458-1 DP in its output area of the P bus. Block S7RD_P reads this data from the P-Bus and provides it, via its pointer interface, to the read blocks (DRD…, CPY_Y) for further processing in the CFC configured software. Mode of operation This block operates similar to the telegram block CRV_P. A maximum of 128 bytes can be accessed via the pointer interface. These bytes are sent from the SIMATIC-CPU to the FM 458-1 DP via the P bus. Data can be read using the read blocks (DRD…) or the copy block (CPY_P). This block only communicates with a SIMATIC-CPU. This means that the required byte or word swap operations are automatically made (depending on the data type of the connected read/write blocks). The entry, which is normally required at the SW-connection of the read/write block, is not evaluated and is therefore not required.

Mode of operation This block operates similar to the telegram block CTV_P. A maximum of 128 bytes can be transferred via this pointer interface and via the P bus to the SIMATIC CPU. This data is previously loaded into the telegram buffer using write blocks DWR… of the copy block CPY_Y. This block only communicates with a SIMATIC-CPU.

Mode of operation The function block is a read/write memory for a REAL value. It is only active, if a 0 at output QF indicates that the memory space in the NOVRAM is available. The function block operating mode is selected at input M: Write operating mode (M = 1) • The quantity to be saved is entered at input X. It is transferred to output Y. • Further, input quantity X is entered in the NOV-RAM of the module. In this case, a value, already contained in the NOV-RAM is overwritten. Read operating mode (M = 0) • The last input quantity, saved in the write operating mode, is output at Y. • The NOV-RAM is deleted from the operating system each time the configured software changes (even when the system is configured for the first time), i.e. zeros are written into it.

Mode of operation The function block initiates a process interrupt at the associated S7 CPU. The IFO double word is transferred to the S7-CPU as supplementary interrupt information. NOTE A process interrupt is only acknowledged after the process interrupt OBs (organization block) has been executed on the S7-CPU. The block does not wait for the acknowledgment. The OB is parameterized in the HWConfig for the associated S7-CPU. The process interrupt is only initiated, if the S7-CPU is not processing a process interrupt from the FM 458-1 DP application module. Output QF has the value 1, if a new process interrupt is initiated, although the last process interrupt was still not acknowledged or the block was not configured on FM 458-1 DP. Output QF has the value 0, if the acknowledgment from the S7-CPU has been received, or if input RES has the value 1.

An SLB module is a system hardware component, which can be an ITSL, an EXM 448-1 module or an optional SLB (SIMOLINK Board) of the ITSL module. The @SL central block may only be configured in a cyclic task and once per SIMOLINK ring. The following parameters must be set for an SLB module: • Hardware address SLB (TAD) • Operating mode (MOD) • Node address (ASL), only relevant when operating mode 0 is selected • Send power (POW) for the SLB module Mode of operation 1. The @SL central block executes the following steps while the system is being initialized: − Checks the validity of the value ranges at the input connections − Checks whether additional @SL central blocks have been configured at the same hardware address (input TAD) − Initializes the SLB module corresponding to the data at the initialization connections Function Blocks - FM 458-1 DP Edition 02.2004 5-1 SIMOLINK drive coupling − Sends an initialization sequence (SIMOLINK) and monitors the starting sequence 2. The @SL central block executes, in the standard mode ("RUN“ operating status) of the system, the following operating steps: − Monitors communications of the SIMOLINK drive interface − Outputs fault messages when communication faults occur at the outputs − Outputs information about the drive coupling − New values for the node address (ASL) and send power (POW) are only transferred after the SIMOLINK drive coupling restarts.
